The sinusoidal loading of an elastic 2 and 3-dimensional half-space is analysed. Such loading arises from the study of rough lubricated contacts. The well-known plane strain solution for internal stresses in the
The proposed techniques are based on storing and reading the sine and cosine components of two sinusoidal functions that are not harmonically related and then evaluating the sine or cosine of the phase difference. The proposed techniques are shown to be very efficient in increasing the effective ...
FM Modulate a Sinusoidal Signal Copy Code Copy Command Set the sampling frequency to 1kHz and carrier frequency to 200 Hz. Generate a time vector having a duration of 0.2 s. Get fs = 1000; fc = 200; t = (0:1/fs:0.2)'; Create two tone sinusoidal signal with frequencies 30 and 60...
A frequency response describes the steady-state response of a system to sinusoidal inputs of varying frequencies and lets control engineers analyze and design control systems in the frequency domain. To understand why the frequency domain is important consider an acoustic guitar. If we place a ...
The first sinusoidal signal has a frequency of 500 Hz (or 0.125 in normalized frequency units) and the second sinusoidal signal has a frequency of 1000 Hz (or 0.25 in normalized frequency units). Get frameLen = 256; sin_500Hz = dsp.SineWave(Frequency=500,SampleRate=Fs,... SamplesPer...
As analyzing sinusoidal functions is easier than analyzing shaped functions, this method is very useful and widely used. A number of mathematical transforms are used to analyze time functions; these are referred to as frequency domain methods. Signals can be transformed from the time to the ...
Examples of 2D sinusoidal functions and their Fourier transforms are shown in Fig. 1. The top figures show a transform pair of a sinusoid of fairly low frequency. The Fourier transform, which contains two Dirac impulse functions, is shown to the left and may be expressed as Sign in to down...
The fitting of these data points is achieved through solid blue lines for transmittance and dashed red lines for reflectance, both of which are modeled as envelopes of sinusoidal functions Full size image Here, the background counts are measured at the signal and idler channels by blocking the ...
These high-frequency signals are subsequently captured by detectors, leading to interference in the video transmission process. As evidence, when pure low-frequency sinusoidal light is used as the interference signal, no disruption to the signal occurs (Supplementary Movie 6). Owing to the ...
